This invention relates to door checks, having for its obj ecttheprovision of an improveddevice of the kind describedembooly- 'ingcertain added convenience in'operation.

2 1 Another objectis to provide a door check which may be operativelvapplied without first returning the door to closed-position, or themanipulation' oflatches. d v OtherYD jects "and advantagesof the con- 1istruction employed'willappear more fully fin the hereinafterdetailslwhen taken in connection with the accompanying drawing in w i lv I Figure l is a front elevation of a doora nd I casing; showing'myinvention attached there- Fig.2 is an elevational view of the device asapplied to adoor in closed position.

In the drawings; 10 designates. a door -hingedlys ecu'red to a frame 11.The device embodying myinvention comprisesqa plate 12 secured by screws13 to thev door 10, the plate being formed withvanintegral latch 14:having a substantially arrow shaped head 15, I the -projectingshoulders16 of whichserve as meansto lock the latch in secure position in coiledportions 24: wound about pins 25 also while permitting however thechannel .17, formed between a pair of 'formedintegral'with the marginaledges of the plate 22. The springs 23 have U-shaped -yoke portions 26which serve to press the.

wings 18 and l9 'yieldingly again'stthe face i of plate 22, the largecentral slot 27 of which 1s overlapped thereby. The plate 22 at one endis provided with a pairlof perforated lugs 28,129 which register with apair of corheld'to the door frame by screws 33. Pivot pins 84;. passedthrough the lugs 28, 29, 30, and 31 serve ashinges on which the keeperassembly swings.

responding 111g s;30,31 formed on a bracket 32 It will be observed thatthe deviceas illus trated in Figs. 1,. 2 and 3 is also provided with ahinged locking button 36 which serves, when desired, as anauxiliarylockingmeans tolbe passed through thechannel 17 and thenposition nel-l'Z. r The operation of the. device described andillustrated is as followsi Assuming the door to be ajar. the keepermember may be swung to engage the wings 18 and 19 with thehead 6 whereinthe projecting shoulders are locked against withdrawal from the, channel17 v longitudinal movement therein.' One oflthe chief. advantages ofthe'pre'sent construction resides inthe-fact that if an unauthorizedperson should; endeavor to force his way into a house, assuming the doorto be slightly ajar,

turned at right angles to the keeper wings;18, .119 which can nowbereleased only'whenthe elongated headof the button is turned into aparallel withthe walls of the chanthe householder may-snap the keeper'inember over the'locking latch head 15 even while the door is aj ar';Heretofore in actual prac ;tice it has either beenlnece'ssary tolreturnthe door is slightly ajar, itwill be diflicult to repel an unauthorizedperson in cases where it would be required to first close the dooragainst the aggressions of a desperate character without the provisionof means of the type now disclosed.

It is to be understood that variations and modifications may be madeinform, proportion, and arrangement of the parts as shown and described;hence, I do not confine myself to the precise details save to the extentthese are circumscribed within the scope of theappended claims; g s vWhat I claim as new and desire to secure by Letters Patent is: n

1. In a device of the kind described, comprising in combination, akeeper and alatch, said keeper having-a longitudinal slot and means tolock said latch in said slot by means of a plurality of resilientmembers hingedly attached to said keeper, saidmeans including an elementsecured to said latch and slid-ably confined between said resilientmembers when in operative position. k I

2. A door check comprlsing 1n combination, a keeper hingedly secured toa door frame, a latch member secured to a door-in said frame, a pair ofwing membershinged to said keeper, saidwing members yieldingilyreceiving said latch, said latch being locked within said keeper afterthe wing members have yielded to a predetermined extent to admit a headelement secured to said latch.

3. In a device of the kind described, in combination, a keeper hingedlysecured to a door frame, said keeper having a slot partially closed byapair of wing members, a latch secured to a door insaid frame, saidlatch having a shoulder head received in the slot, said wing membersyieldingly receiving and locking said shouldered head wliile permittingthe entrance of said shouldered head into the slot at any point withinthe limits defined by said wing members, without the return of the doorto closed position.

pelling said strips against the face of said plate but divergingtherefrom as said keeper member is pressed thereagainst.

5'. In a device of the kind described, in combination, a plate hingedlysecured to a bracket fastened to a door frame, said plate having alongitudinal slot, said slot being overlapped by a pair ofstripsswingingly attached to said plate and resiliently pressed against theface of the plate by a pair of springs secured on the margin of theplate,

'saidystrip's defining a comparatively narrow channel therebetweenregistering with the I said slot, a keeper member integrally formed 7with a plate secured to a door, said keeper member having a shoulderedhead adapted to enterthe channel between the strips while pressing backsaid strips to a point where the shouldered head of the keeper passesout of contact with the strips, said strips then returning to normalposition against the face of said plate and thereby slidably locking thekeeper within the plate.

6. In a device of the character described, cooperating latch and keeperelements having provision for relative longitudinally slidableinterlocking engagement, said elements relatively provided withyieldablemeans whereby one member may be snapped laterally into engaging relationto the other member at any point within the range of the permittedrelative longitudinal movement.

7. In adevice of the character described, a latch element and acooperating longitudinally slotted keeper element, oneofsaid ele-, mentshaving yieldable means whereby said latch element may be pressed intoengagement with the slotted portion of said keeper into slidableinterlocked working engage ment at any point within the length of theslotted portion of said keeper element.

9. In a device of the character described, a hinged longitudinallyslotted keeper element, said keeper element having ayieldable .120

supporting member coincident with'the 1on gitudinal wall of its slottedportion, and a latch element having a shouldered extension adapted to bepressed transversely through the slotted portion of said keeper:element. whereby to be retained in slidable interlocked relation tosaid yieldable member at any pointwithin the length of the latter.

10. Ina device of the character described,

a keeper to be .hingedly secured to a door p:

- Within the length of the slot.

11. In a device of the character thereof, said latch element having ashouldered projectionextending beyond the edge of'the door, a keeperhingedly secured to the door frame adjaoent'to said latch element, .saidkeeper having a longitudinal slot open at its end adjacent'to the hingedend portion of the keeper, said shouldered pro jection of thelatchelement being engageable With the slotted portionwof saidkeeper'element when said element is in a positlon substantiallyperpendicular to the door frame and the door isclosed, and yieldablemeans whereby" said shouldered projection is permitted to enter saidslot in the keeper element at any point withinthe limits defined by thelength of said slot when the door is open In testimony whereof Ihave'signed my described,

in combination with a door'frame and a door hingedly mountedin saidframe, a latch element mounted on the door at the swing side
